I have a Lenovo Legion 7 16ACHg6 that for a week decided not to detect any external HDMIs nor other types of cables. It is a dual booted laptop with Windows 10 on another disk (disabled Secure Boot, Dynamic graphics).
Software specs
$ uname -a
Linux Legion-7-16ACHg6 5.15.0-56-generic #62-Ubuntu SMP Tue Nov 22 19:54:14 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux
Whenever I connect an HDMI, USB-C or other type of monitor output there is not detected whatsoever.
$ xrandr

The laptop is currently using recommended NVIDIA drivers v525

Also when I run nvidia-smi I get (I found nvidia-smi “No devices were found” on NVIDIA forum but couldn't understand if there were a solution other than try to update)
$ nvidia-smi
No devices were found
and examining the dmesg output
$ dmesg

What I tried
I have already tried updating ubuntu-drivers
sudo ubuntu-drivers autoinstall
I tried re configuring gdm3
sudo dpkg-reconfigure gdm3
I tried commenting out options nvidia-drm modeset=1 in /lib/modprobe.d/nvidia-kms.conf file and leaving Power mode. I am currently running on Balance mode.
A brief personal comment
Citing a very similar question (and also looking at the amount of questions arising in this realm of NVIDIA-HDMIs-graphics-drivers-etc.)
Aside from these considerations, thanks, as always, to the community.
